The present study systematically investigates a direct method for synthesising copper oxide nanoparticles (CuONP) utilising the defensive gland secretion of the beetle Luprops tristis Fabricius (L. tristis) using a greener method under microwave irradiation. By employing the unique biological approach of utilising the insect L. tristis, we successfully characterised the CuONP abbreviated as LCuONP through […]
